[#1111] TIAuddec1 muted during playing back

Details
I am using gstreamer on DM6446 EVM to receive and playback RTSP streamings. The
pipeline is like

rtspsrc ! rtpmpadepay ! &lt;aud_dec&gt; ! alsasink sync=true.

1. if TIAuddec1 is used as &lt;aud_dec&gt;, things will be fine till
gstrtpjitterbuffer complains about &quot;Packet lost&quot;. Whenever
that happens, the sound is muted while debugging shows that the
aud_decode_thread is still running.

2. if TIAuddec1 is used as &lt;aud_dec&gt;, but alsasink has sync=false,
the sound can survive from the above gstrtpjitterbuffer packet lost. But there
is about 2 seconds delay always.

3. if mad is used as &lt;aud_dec&gt;, sound survives the
gstrtpjitterbuffer packet lost situation regardless the alsasink
sync=true/false.

4. run a similar pipeline on the video side with TIViddec2 as the vid_dec gives
good video playback and survives the gstrtpjitterbuffer packet lost situation
regardless the TIDmaiVideosink sync=true/false.

So, I _guess_, TIAuddec1 does not handle some cases when upstream has errors.
Please shed some light on how to debug it. Thanks!
